import csv into elasticsearch

You can download it with pip:

pip install elasticsearch-loader

And then you will be able to load csv files into elasticsearch by issuing:

elasticsearch_loader --index incidents --type incident csv file1.csv

Additionally, you can use custom id file by adding --id-field=document_id to the command line

Good job, you're almost there, you're only missing the document ID. You need to modify your elasticsearch output like this:

elasticsearch {
    action => "index"
    hosts => ["127.0.0.1:9200"]
    index => "simpsons"
    document_type => "episode"
    document_id => "%{id}"             <---- add this line
    workers => 1
}

After this you'll be able to query episode with id 10

GET http://localhost:9200/simpsons/episode/10
